The remote possibility of "tipping the scales" assuming all matches have a 50-50 chance of winning... it's worth it. Whether it is using a UAV to spot the enemy presence, or to use arty on Mordor to stop enemy entry into the dome.
It's a sunk cost, admittedly, but sometimes it is the difference between success and failure.
In the particular case of the UAV, you can recover some of money through the basic rewards for winning/losing (25000) and the UAV detection bonus. Anything else you get is a "bonus" IMO. If you simply "break even", you would have collected XP over that time which is imperative for accelerating XP growth in a light mech.
Also one other thing... I know PGI has posted (through Twitter IIRC) what their reward numbers are per class on average, but unfortunately I believe the UAV influences lights more (since they can reach their destinations quicker and are usually in a better position to deploy them), so it affects their earnings in an "inflated" way.
It is a contextual thing though and I'm sure people will disagree, but the UAV has always been a reliable source of money growth for me, even if I have to pay for it. Arty deployments require being extra selective.
Remember that winning guarantees salvage... so that's something to really think about in the cost analysis. If you consider that Salvage consists of like 10k on average, you're "making back your money" in theory.... only for ONE consumable though.
Also, I'm not sure if this is still true, but last time I had my Conquest vs Assault gains calculated, I got on average 10k more on Conquest than Assault. Although I'm unsure if that's still the case now, but I would not just "write it off". The more time you spend in Conquest, the more likely your payout is, especially if you win.
If you are wasting your consumable though (like using it to just use it), you are wasting money.
